An article transfer apparatus comprises a reciprocating pusher 66, 66SP1/SP to transfer articles from an incoming conveyer 59, 59SP1/SP to an outgoing conveyer 64 and a store 45, 45SP1/SP whereby articles may be stored or released to smooth out the supply and demand of the respective conveyers. The articles moving on the conveyer 59, 59SP1/SP are passed beneath a sensing element (112) (Fig. 3, not shown), which causes a microswitch (MC1) to open when a row of articles has formed against a stop 70, 70SP1/SP, which is subsequently raised by energization of an electromagnet 76, 76SP1/SP. The articles are advanced against a stop 69, 69SP1/SP, after which the pusher 66, 66SP1/SP is moved forward by means of a roller 47, 47SP1/SP, to which the pusher is connected via linkage, engaging in a groove 46, 46SP1/SP in a cam 20, 20SP1/SP mounted on a main shaft 15. The articles are pushed beneath a roller 68, 68SP1/SP onto an elevator 44, 44SP1/SP against a plate 92, 92SP1/SP which is cammed upwards by a cam 21, 21SP1/SP on the main shaft 15 engaging a roller 79, 79SP1/SP. The articles still on the conveyer 59, 59SP1/SP are held stationary by the transverse edge of the pusher 66, 66SP1/SP, during a dwell in the movement of which the plate 92, 92SP1/SP is cammed downwards, whereupon the pusher 66, 66SP1/SP is moved further forward to push the row of articles onto the conveyer 64 leading to a wrapping machine, the motor (M) of which is started by the articles engaging a microswitch (MC). The pusher 66, 66SP1/SP is then returned to the edge of the elevator 44, 44SP1/SP, moved forward again a short distance, stopped and finally returned to its starting position. If articles are absent on the conveyer 59, 59SP1/SP, the microswitch (MC1) is closed energizing the electromagnet 76, 76SP1/SP to lower the stop 70, 70SP1/SP across the conveyer 59, 59SP1/SP. The microswitch (MC1) is actuated each time an article is passed beneath the sensing element (112) but due to a capacitor (C 3 ) the stop 70, 701 remains lowered until a complete row of articles has accumulated. With the microswitch (MC1) closed, an electromagnet 101, 101SP1/SP is energized to open tooth elements 95-96, 95SP1/SP-96SP1/SP allowing a layer of articles in the store 45, 45SP1/SP to fall onto the elevator 44, 44SP1/SP, the plate 92, 92SP1/SP being cammed upwards to align the articles. After lowering of plate 92, 92SP1/SP the row of articles is moved onto the conveyer 64 by the pusher 66, 66SP1/SP. When the store 45, 45SP1/SP is empty a microswitch (108) is actuated by sensing members 104-105, 104SP1/SP-105SP1/SP to cause the wrapping machine to stop. If the wrapping machine is inoperative, an electromagnet 32, 32SP1/SP is energized causing its armature 33, 33SP1/SP to engage a groove 36, 361 in a cam 18, 18SP1/SP, which is displaced on the main shaft 15 to cause a roller 38, 38SP1/SP, mounted on a rod 40, 40SP1/SP connected to the elevator 44, 44SP1/SP, to be engaged within a groove 37, 37SP1/SP of a cam 19, 19SP1/SP. The articles resting on the elevator 44, 44SP1/SP are thus raised into the store 45, 45SP1/SP, after completely filling of which a microswitch (109) is actuated by a sensing member 106, 106SP1/SP to cause the supplying machine to stop. Microswitches (MC2-MC6) actuated by cams 23-28 keyed on the main shaft 15, participate in the cyclic operation of the apparatus.
